How do you know when you are getting older?

When I arrived to work yesterday, there was a phone book left. I picked it up from the door and put in on the back counter .
Later, I was doing some detective work and needed to call my neighboring stores. I used the phone book since my cell was locked up.
I made the calls and my asst manager said to me , I wouldn't even know how to use the phone book.
I said its easy, it alphabetical. You just need to know how to spell it, there is no spell check..lol
